The nonprofit announced Jackson will be its inaugural social and family justice fellow. In naming Jackson to the three-month post, Imari Paris Jeffries, the organization’s executive director, highlighted the former councilor’s expertise in public policy, advocacy, and public service, adding that those skills “will help shape a vibrant future for families.”

“Tito is a champion for the families of Boston and has demonstrated a commitment to social justice, communities of color, and empowering people to be their own champions,’’ Jeffries said.

Jackson called the appointment “a tremendous honor” and said it dovetails with the issues he focused on during his six years on the council.

“All too often, communities of color face barriers beyond the everyday trials and tribulations of parenting,’’ Jackson said. “My work with Parenting Journey will help break down obstacles and enable parents and caregivers to build strong, resilient families and communities.”

As a councilor, he chaired the Committee on Education and the Special Committee on the Status of Black and Latino Men and Boys. He was vice chair of the council’s Committee on Healthy Women, Families and Communities.

Prior to his elected role, he led former governor Deval Patrick’s reelection campaign and worked in pharmaceutical sales.
